HOW TO ERASE DTC (WITH GST)NCAT0020S041. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªOBD SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC section ªGeneric Scan Tool (GST)º.
HOW TO ERASE DTC (NO TOOLS)NCAT0020S051. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
Refer to EC section ªHOW TO SWITCH DIAGNOSTIC TEST MODESº.
Malfunction Indicator (MI)NCAT00211. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
IIf the malfunction indicator does not light up, refer to EL sec-
tion (ªWarning Lamps/System Descriptionº, ªWARNING
LAMPS AND CHIMEº).
(Or see MI & Data Link Connectors in EC section.)
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (OBD) malfunction. For detail,
refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM
DESCRIPTIONº).
CONSULT-IINCAT0022After performing ªSELF-DIAGNOSTIC PROCEDURE (WITH CON-
SULT-II)º (AT-19), place check marks for results on the ªDIAGNOS-
TIC WORKSHEETº, AT-31. Reference pages are provided follow-
ing the items.
